That is my experience. They only seem to ticket based on the two hour time limit. I see tons of cars parked way to close to the intersection all of the time and they seem to do nothing about it.

I have a theory that it has to do with the app they use to scan license plates to determine if you have a permit. I assume that the app automatically tags the time and location for each scan and when it detects a same location over the two hour limit for a tag it prints the ticket with no or little action required by the agent. However, if the agent wants to give a ticket for something like parked to close to the curb they have to take a picture, enter data, etc.
